The R3 that ended Alexandra's TMJ headaches, 90 days in.
Alexandra has a TMJ disorder. She grinds and clenches all night, and it got bad enough that she chipped a tooth in her sleep and chewed straight through her retainers, roughly $150 a time even with insurance. She used to wake up with tension headaches and jaw pain rough enough that it hurt to smile or talk. She found the Reviv R3 on her Facebook feed, went down a rabbit hole of reviews, and tried it. It is soft food-grade silicone, flat, with holes so she can breathe, and it supports her jaw instead of just holding her teeth apart. 90 days later the headaches and jaw pain have faded, she clenches less even during the day, and her retainers have stopped disappearing.

The R3, the flat-plane guard behind her results
Worn while you sleep
Overnight, plus a few daytime hours if you want to move faster. No routine to learn.
Gentle, steady pressure
The flat-plane design supports the jaw without locking your bite, so it can settle where it should.
Ready out of the case
Premium soft silicone, food-grade tested. No boiling, no moulding. Backed by a 1-year warranty.
How did the R3 help Alexandra?
The three changes she comes back to most. Her experience, not a promise.
No more tension headaches
The TMJ headaches and jaw pain that used to greet her every morning faded once her jaw was supported through the night. "I am not waking up with tension headaches, I am not waking up with jaw pain."
Done chewing through retainers
She chewed through retainer after retainer at about $150 each, and chipped a tooth in her sleep. That stopped. "No more chewing through plastic retainers every couple of months."
A calmer jaw, even in the daytime
Soft food-grade silicone, no boiling and no moulding, with holes so she can breathe. She noticed the calm carried past the morning. "My jaw was just more relaxed and I was not even clenching as much during the day."
Three steps. All of them easy.
Take it out of the box and wash it
Wear it to sleep and 2–3 hours during the day
Wash it and let it dry
Confused about size? Measure your width.
One measurement decides it: the width across your back molars.
Width · molar to molar
| Size | Width, molar to molar |
|---|---|
| Medium | 50 mm or less |
| Large | 51 to 56 mm |
| XL | 57 mm or more |
Tips: use a crisp, firm apple, make sure your teeth are clean and dry, press down evenly, and measure carefully in millimetres. No apple? Cut a piece of cardboard to the shape of your upper arch, or measure the width of a current retainer.
Need help on how to measure?
Watch how to measure your palate size with the simple bite-and-bread method:
Consistency is the whole game
- Weeks 1-2: the adjustment phase. A little soreness or extra saliva is normal, your soft tissue is adapting, not a sign anything's wrong.
- Build up gradually: shorter daytime sessions first, then overnights. Ease off for a bit if it ever gets sharp.
- Over the months: the changes Alexandra talks about, fewer headaches and a calmer jaw, came from wearing it consistently, not from wearing it harder. Her own update is at 90 days.
What people say about the R3
Questions, answered
How should I start? ›
Wearing it: the standard pattern is overnight plus 2 to 3 hours during the day. Build up gradually with shorter daytime intervals first. The early phase is the hardest and gets much easier after a few weeks.
Early discomfort: sore teeth, achy gums and extra saliva in the first weeks are the soft tissue adjusting, not a problem. Take breaks if it gets sharp, don't push through pain.
Faster results: consistency first, then simple stretches like Bite and Hold alongside the guard.
How does sizing work? ›
Width matters most. Measure the outer edges of your upper molars at their widest point, shown in this size guide.
Medium (46mm) fits teens and smaller mouths, Large (53.6mm) fits most adults, and XL (59.6mm) is for larger mouths.
Why does it work? ›
Think of the soft tissue over the skull like a balloon. Grinding your teeth down deflates it over time, what we tend to call "aging." Adding height back with gentle, consistent pressure runs the same physics in reverse.
How many people have done this? ›
Over 30,000 people have started using Reviv appliances and this method.
What is it made of, and what's included? ›
Premium soft silicone, food-grade tested. Your order is the R3 in your chosen size and colour, with its storage case and instructions, backed by a 1-year warranty.
